Back to
Hardener page
Product Description:
A long pot life laminating hardener for use on large parts. Exhibits very low exudation allowing for secondary bonding with minimal preparation. Low odor and low to moderate skin toxicity for wet lay up laminating. Cured material has >185°F HDT without a post cure allowing finished laminate to be used elevated service environments. Easy to use 4:1 volume (100:22 by weight) mix ratio. 100% solids, zero VOC’s.
Product Uses:
Composite parts and tooling made by hand lay up and vacuum bagging. |
